Description
CROSS-REFERENCE TO RELATED APPLICATIONS
[0001] This application is a continuation-in-part of U.S. patent
application Ser. No. 11/488,957 to Bevirt et al., filed Jul. 19,
2006, which is hereby incorporated by reference in its
entirety.
BACKGROUND
[0002] 1. Field of the Invention
[0003] This invention relates to wireless communication, and more
specifically to improvements in wireless headsets for use with
cellular telephones and similar devices.
[0004] 2. Description of Related Art
[0005] A headset may be used in conjunction with a telephone device
for several reasons. With a headset, the user is relived of the
need to hold the phone and thus retains his or her hands free to
perform other functions. Headsets also function to position the
earphone and microphone portions of a telephone close to the user's
head to provide for clearer reception and transmission of audio
signals with less interference from background noise. Headsets may
be used with telephones, computers, cellular telephones, and other
devices.
[0006] The wireless industry has launched several after-market
products to free the user form holding the phone while making phone
calls. For example, various headsets are manufactured with an
earpiece connected to a microphone and most of these headsets or
hands-free kits are compatible with any phone brand or model. A
possible headset can be plugged-in to the phone and comprise a
microphone connected via wires to the headset so that the
microphone, when in position, can appropriately capture the voice
of the user. Other headsets are built in with a Bluetooth chip, or
other wireless means, so that the voice conversation can be
wirelessly diverted from the phone to the earpiece of the headset.
The Bluetooth radio chip acts as a connector between the headset
and a Bluetooth chip of the cell-phone.
[0007] An important aspect for headsets is that they be able to fit
the head and facial geometry of a variety of users, yet most
headsets typically do not allow for adjustment to meet variations
between users. Also, a headset may be more convenient if there is
an easy way to carry it with the user when the user desires not to
have it mounted on the ear.
[0008] What is called for is a headset which enhances the ability
of the user to adjust the headset geometry to fit the user's head
and face, as well as a headset which enhances the convenience of
using and storing the headset.
SUMMARY
[0009] A headset which includes a metal or metallic housing to
which various accessory components can be attached. These
components can include an ear loop, a necklace for the holding of
the headset while not being worn on the ear, an external mount, and
other components. The components include a magnet which facilitates
mounting to the headset. The components are not restricted to a
particular attach point, which enhances the ability of the user to
adjust the geometry for better fit.

DETAILED DESCRIPTION
[0021] FIG. 1 illustrates a headset 150 according to some
embodiments of the present invention. The main body 151 may consist
of an inner housing 153 and an outer housing 152. The inner housing
153, which is the side of the main body 151 adjacent to the user's
head, may be made of a magnetically permeable material to allow for
the attachment of accessories using a magnet. The use of a
magnetically permeable material such as a metal housing may give an
additional advantage of allowing for a very thin wall thickness
which may facilitate the construction of a very small headset. The
headset may be used in conjunction with accessories which use a
magnet to attach to the housing. An earpiece 159 is attached to the
main body 151. One or more buttons 151, 154 may be positioned on
the outer housing 152 of the main body 151 and may be used to
implement functionalities of the headset 150. An LED panel 155 may
indicate function. A microphone 156 is seen.
[0022] In some embodiments, the microphone may be a deployable
microphone that deploys with the use of a microphone boom. The
microphone boom may be stowed into the main body 151. The
microphone is seen to be at an inner edge of the main body 151, and
not in the center of the main body. In some embodiments, the
microphone boom may stow into a position along the main body.
[0023] Although the present invention has been disclosed using
embodiments of wireless headsets, other types of headsets including
wired headsets may be utilized in other embodiments.
[0024] Referring to FIGS. 1 and 3, the earpiece 159 consists of an
earpiece base 157 and an ear engaging body 158. The earpiece 159
may be attached to the main body 151 with a flexible joint. The
flexible joint may allow the relative position and angle of the
main body of the headset and the earpiece to be adapted for users
with differing ear shapes and geometries. The ear engaging body 158
may be adapted to fit into the ear canal of the user, and may be
adapted to support the headset on the user's head without
additional attachments in some embodiments. In some embodiments,
additional attachments may be used with the headset.
[0025] FIG. 2 is a sketch illustrating a headset 200 with an
attached ear loop 205. The headset 200 has a main body 201 which
has an inner housing 203 and an outer housing 202. An earpiece 209
is attached to the main body 201 with a joint 210. In some
embodiments, the joint 210 is a flexible joint. In some
embodiments, the joint 210 is a ball and socket joint. The surface
204 of the inner housing 203 provides a mounting plane for an ear
loop 205. The ear loop 205 has an ear hook 207 adapted to be worn
over the user's ear to assist in the wearing of the headset 200.
The ear loop base 206 supports the ear hook 207 and provides an
attachment to the inner surface 204 of the inner housing 203. The
ear loop base 206 has a magnet 208 which allows for the attachment
of the ear loop 205 to the inner surface 204 of the inner housing
203. The inner housing 203 is made from a magnetically permeable
material which allows the attachment of the magnet 208 to the
surface 204 of the inner housing. In some embodiments, the entire
inner housing is made from a material to which a magnet will
adhere. In some embodiments, all or part of the surface 204 of the
inner housing 203 is made from a material to which a magnetic
material will adhere. The term magnetically permeable as used
herein refers to a material to which a magnet will attach in the
context of this application. In some embodiments, there may be a
magnetically permeable layer on or under the surface of the inner
housing. In some embodiments, the magnetically permeable layer is
under the surface 204 and is substantially parallel to the surface
of the inner housing. In some embodiments, a magnetically permeable
portion may be on the surface or below the surface. The
magnetically permeable portion may be composed of wire loops or
other means.
[0026] The ear loop base 206 may be positioned by the user to a
position that better fits the particular geometry of the user's ear
and head. The distance 211 between the earpiece 209 and the ear
loop base 206 may be altered by the placement of the ear loop base
206 on the surface 204 of the inner housing 203. The ear loop base
206 may be moved vertically 212 or horizontally 213. The magnet 206
attaching the ear loop base 206 to the inner housing 203 may be of
a strength that allows relatively easy removal from the headset but
of sufficient strength that the ear loop 205 will not dislodge from
the headset while being worn by the user in normal operation.
[0027] The headset can be used by the user in a geometry that best
suits the user. In addition, the ear loop may be removed from the
main body should the user so desire. The headset may be worn using
just the earpiece as the attachment to the user in some cases.
However, the user may desire a more secure attachment to the head
and then can utilize the removable ear loop as well. In addition,
the removal of the ear loop may allow for safer storage of the
headset when not being worn. The magnetically permeable surface on
the main body also allows for attachment of other accessories, or
methods of storage, with the ear loop either still attached or
removed.
[0028] FIG. 4 illustrates an exploded view of a headset 400
according to some embodiments of the present invention showing a
flexible joint between the headset main body and the earpiece. A
headset 400 has a main body 408 adapted to receive wireless
communication. A microphone 420 is seen at the far end of the
headset main body 408 from which an earpiece junction 402 is
attached. The microphone 420 is seen in close proximity to the
headset main body 408, but may have an extendable boom to deploy
the microphone closer to the mouth of the user.
[0029] The earpiece junction 402 attaches the main body 408 to the
earpiece 401, seen in exploded view in FIG. 4. The earpiece
junction 402 is attached to the main body 408 along the interior
surface 421 of the main body. The attachment of the earpiece 401 to
the earpiece junction 402 creates a flexible joint which allows for
the adjustment of the position of the earpiece relative to the main
body. The earpiece may then be adjusted by the user to best fit the
user. In some embodiments, the earpiece junction 402 is a ball and
socket configuration which includes a socket engaging end surface
422 which is mated into an internal socket receiving cavity
attached to the base 405 of the earpiece 401. The mated flexible
joint allows for movement in three orthogonal axes. In some
embodiments, the relative positions of the two sides of the
flexible joint may be reversed; the socket engaging end surface may
be on the earpiece side and the cavity may be attached to the main
body of the housing. In some embodiments, the internal socket
receiving cavity 406 is substantially residing within the base of
the earpiece.
[0030] The socket engaging end surface 422 has a central hole 403
through the earpiece junction 402 in some embodiments. In some
embodiments, the central hole 403 is a conduit through which wires
pass to a speaker within the earpiece. In some embodiments, the
central hole 403 is a sound channel through which sound is
channeled from a speaker on the main housing side of the flexible
joint. The ear engaging body 407 is adapted to fit into the ear
canal of the user and to support the headset 400 on the user in
some embodiments. Although described in the context of a speaker,
the audio device may be a driver or other appropriate device.
[0031] With the combination of adjusting the relative angle of the
earpiece to the main body, as well as the position of the ear loop
relative to the earpiece, the user is able to adjust the headset to
maximize fit and comfort.
[0032] Although the illustrations of embodiments show an earpiece,
in some embodiments the headset may not have an external earpiece.
For example, the headset may have a flush mounted, recessed, or
raised speaker (or other audio driver) on the main body of the
headset. The movable ear loop assembly may be used with such a
headset as well.
[0033] FIG. 5 illustrates the headset 150 with the microphone 156
in the deployed position. The microphone 156 can be seen now
deployed from the main body 151. The microphone 156 has been
deployed with an extendable microphone boom 162 which was stowed
within the main body 151. The microphone boom 162 consists of a
first boom section 160 and a second boom section 161. The
microphone boom 162 is a telescoping boom in this embodiment; the
second boom section 161 stows into the first boom section 160 when
the microphone boom 162 is stowed. In some embodiments, both boom
sections are made from a superelastic material. In some
embodiments, one or both of the boom sections may be curved in
their deployed state. In some embodiments, the boom may be
restricted from rotation relative to the main body 151. In some
embodiments, the boom sections may be restricted from rotation
relative to each other. This may be accomplished by having the
telescoping sections be made from an oval profile, or through other
methods. In some embodiments utilizing a telescoping microphone
boom, the microphone boom may be substantially longer than the
length of the main body of the headset along its long axis. For
example, the main body of the headset, with the microphone stowed
and the microphone boom within the main body, may be approximately
2.5 inches in length. The microphone boom may extend out
approximately 4 inches in such an embodiment. In some embodiments,
the second boom section 161 is curved in its relaxed state, and the
first boom section 160 is straight. The second boom section 161 is
straightened as it is stowed back into the first boom section 160,
and in turn as both boom sections are stowed back into the housing.
In some embodiments, the microphone boom is made from a single
section, or a plurality of sections.
[0034] The user may choose to partially deploy the microphone based
upon the user's preference, or also based upon the user's head size
and shape. The partial or full microphone deployment, in
combination with the adjustable ear loop, or in combination with
the adjustable ear loop and the flexible joint of the earpiece, or
some combination of all of the above, gives the user the ability to
adjust the headset for best fit and function.
[0035] FIGS. 6A-C illustrate a headset 600 with an movably attached
ear loop assembly 605 with an extendable microphone boom in the
deployed position. The headset 600 has a main body 601 which has an
inner housing 603 and an outer housing 602. An earpiece 609 is
attached to the main body 601 with a joint 610. In some
embodiments, the joint 610 is a flexible joint. In some
embodiments, the joint 610 is a ball and socket joint. The surface
604 of the inner housing 603 provides a mounting plane for an ear
loop assembly 605. The ear loop assembly 605 has an ear loop 607
adapted to be worn over the user's ear to assist in the wearing of
the headset 600. The shape of the ear loop may vary, as discussed
below. The ear loop base 606 supports the ear loop 607 and provides
an attachment to the inner surface 604 of the inner housing 603.
The ear loop base 606 has a magnet within it which allows for the
attachment of the ear loop assembly 605 to the inner surface 604 of
the inner housing 603. The inner housing 603 is made from a
magnetically permeable material which allows the attachment of the
magnet in the ear loop base 606 to the surface 604 of the inner
housing. In some embodiments, the entire inner housing is made from
a material to which a magnet will adhere. In some embodiments, all
of part of the surface 604 of the inner housing 603 is made from a
material to which a magnetic material will adhere. The term
magnetically permeable refers to a material to which a magnet will
attach in the context of this application.
[0036] The ear loop base 606 may be positioned by the user to a
position that better fits the particular geometry of the user's ear
and head. The distance between the earpiece 609 and the ear loop
base 606 may be altered by the placement of the ear loop base 606
on the surface 604 of the inner housing 603. The ear loop base may
be moved vertically or horizontally. The magnet attaching the ear
loop base to the inner housing may be of a strength that allows
relatively easy removal from the headset but of sufficient strength
that the ear loop will not dislodge from the headset while being
worn by the user in normal operation. In some operational modes,
the user will desire to use the headset without the ear loop
assembly attached to the headset. For example, the headset may stay
well mounted to a user's ear during the activity in which they are
engaged, such as sitting or driving. While engaging in other
activities which may more rigorously jostle the headset, the user
may desire to use the ear loop in order to achieve a more secure
fit. Some users may desire to use the ear loop during all use.
[0037] In some embodiments, the magnetically permeable material to
which the magnet of the ear loop base will adhere may not be
external to the main surface of the inner face of the main body.
The magnetically permeable may be a layer under the surface in some
embodiments.
[0038] The microphone 656 has been deployed with an extendable
microphone boom 662 which was stowed within the main body 601. The
microphone boom 662 consists of a first boom section 660 and a
second boom section 661. The microphone boom 662 is a telescoping
boom in this embodiment; the second boom section 661 stows into the
first boom section 660 when the microphone boom 662 is stowed.
[0039] In some embodiments, the ear loop base may be constrained in
its movement along the headset. For example, the ear loop base may
have guides that run along the outside of the housing such that the
ear loop base may move only in a single axis along the length of
the housing. In some embodiments, the guide may be another type of
feature restricting motion is other axes, such as a slot on the
housing with a linear tab on the ear loop base, or other means.
[0040] FIGS. 7A-B illustrate an ear loop assembly 705 according to
some embodiments of the present invention. The ear loop base 706
may have a hole 710 in a raised center 711 into which the ear loop
707 is inserted and captured with a friction fit. The first section
714 of the ear loop 707 may be predominantly straight in order that
it can be slid further into the hole 710, allowing for the user to
customize the sizing and fit of the ear loop. A second section 713
of the ear loop 707 may be curved in order to better fit the ear of
the user. In some embodiments, the first section and the second
section of the ear loop are of a spring material, such as stainless
steel. In some embodiments, the first section 714 may be of a
spring material, and the second section 713 may be of a more
malleable material, allowing for easier bending and forming of the
curved section to better fit the user's ear. In some embodiments,
the ear loop may be made of a super elastic material. The ear loop
may be covered with a heat shrink tubing or other material for
reasons of comfort or for other reasons. The ear loop may have an
end cap 712 which may be of metal in some embodiments. In some
embodiments, the ear loop and the ear loop base may be a unitary
piece without the functionality of adjustment between the ear loop
and the ear loop base.
[0041] The ear loop base 706 may consist of a magnet coated with a
material such as thermoplastic elastomer (TCE) in some embodiments.
The back surface 716 of the ear loop base 706 may be substantially
flat to allow for better magnetic attachment to the magnetically
permeable surface of the headset to which it will be magnetically
attached. The magnet may be of neodymium iron boron in some
embodiments. The magnet may be 12 mm in diameter and coated with
TPE of a thickness of 0.3 mm in some embodiments. There may holes
717 in the coating through to the magnet in some embodiments. The
friction between the ear loop base and the headset may be adjusted
by varying the type of TCE used on the ear loop base, or by varying
the surface finish of the TCE, or by varying both. The friction may
be selected to be sufficient relative to the magnetic attachment
strength such that the ear loop base may be moved along the headset
to adjust the fit, but also have sufficient friction that the
position of the ear loop base does not move in regular use.
[0042] FIG. 8 illustrates another shape of ear loop according to
some embodiments of the present invention.
[0043] FIG. 9 illustrates a mount for mounting of a headset
according to some embodiments of the present invention. A mount 901
is seen attached to a dashboard 905 of a vehicle. The mount 901 may
be affixed with an attachment layer 902, which may be adhesive,
hook and loop fastening, or other means. The mount 901 has a magnet
904 mounted along its top surface. The magnet 904 may be exposed
along the surface or may be below the top surface with a coating
over it. The headset 903 is seen magnetically attached to the mount
901. A mount may be used in a variety of other locations as
well.
[0044] In some embodiments, the mount may be constrained in its
positioning relative to the headset. For example, the mount may
have guides that limit positioning of the headset relative to the
base to only a single axis along the length of the housing. In some
embodiments, the mount may have a recess adapted to receive the
headset in a single position.
[0045] FIGS. 10A-C illustrate an apparatus for carrying a headset
according to some embodiments of the present invention. A user 301
is seen with a necklace 302 worn around the neck. The necklace 302
has a magnetic clip 303 on it. The magnetic clip includes a magnet
305 adapted for magnetically attaching a headset with a
magnetically permeable surface or layer. The magnet may be exposed
or may be covered with an external layer. The magnet may be a disc
of neodymium iron boron in some embodiments. The magnetic clip 303
allows for the headset 304 to be attached to the user when not in
use.
[0046] In some embodiments, the magnetic clip 303 may be
constrained in its positioning relative to the headset. For
example, the magnetic clip 303 may have guides that limit
positioning of the headset relative to the magnetic clip to only a
single axis along the length of the housing. In some embodiments,
the magnetic clip may have a recess adapted to receive the headset
in a single position.
[0047] FIGS. 11A-B are views of a headset according to some
embodiments of the present invention.
[0048] As evident from the above description, a wide variety of
embodiments may be configured from the description given herein and
additional advantages and modifications will readily occur to those
skilled in the art. The invention in its broader aspects is,
therefore, not limited to the specific details and illustrative
examples shown and described. Accordingly, departures from such
details may be made without departing from the spirit or scope of
the applicant's general invention.
